One of the reasons to collect your own loose hair was to make a hair bun stuffer for their pouf hairstyles.
LOL-- my grandma used to call those "rats", presumably because they were long ovals about the shaped of a rat's body. She said, "We put rats in our hair," and I about died until she explained it.
Then, in the 60s, hair rats came back into style! Especially to get that high pouf at the crown of the head for the Barbra Streisand look.
